Even though Windows Phone market share has appreciably dropped in the last year, I plan on continuing to support and update my app as long as the platform exists.  

Looking at how few Window Phone users there are out there, I'm certainly not doing this for the money. For me, this was more about trying to give something back to the audio community.

I still do believe in Windows Phone. I like some of the things it does different from the other platforms, and I believe that a third phone OS is a good thing. Though with the current market numbers, it's become essentially a two platform market : Apple or Android.

But I believe in doing the things you believe in, sometimes even when the numbers don't look good, so will continue on...

I see Microsoft as sitting out this phone cycle, while it retools Windows -- focusing on the OS software, versus doing any new phone hardware.

Full Windows 10 on ARM with legacy x86 emulation and telephony capabilities, is what I think may save Windows Phone. You can see Microsoft in the last year, increasingly trying to make Windows on mobile just Windows 10 and not a special phone version.

As Microsoft sits out this cycle, phone hardware will grow even more powerful -- so maybe when Microsoft finally has full Windows 10 on ARM with x86 legacy emulation ready, the phone hardware will be able to run the OS easily and your phone could potentially become your only computer -- that would be a game changer.

And with full Windows 10 morphing to support all manner of form factors -- currently from desktops to tablets to notebooks, you could see that expanding to cover new classes of devices with telephony capabilities -- so future phones may end up taking on a range of form factors under full Windows 10.

I think at that point, Microsoft will re-enter the 'phone' hardware market -- maybe finally release a Surface phone or maybe a new class of telephony device... Seeing the talent of the Microsoft Surface team to innovate with their nuanced sensitivity to design, I would bet on them eventually to deliver.

Microsoft would re-enter the market only when they truly had something that would majorly differentiate them from the other platforms and compelling enough to excite potential users.

If you look at the state of current Apple and Android phones, most users are satisfied and there would be no compelling reason for them to switch to another phone platform, unless it was breathtakingly exciting and useful.

What's needed is sometime akin to the magnitude of the first iPhone release back in 2007. That was Apple's very first phone, and there were at the time very established and dominant phone makers. But the first iPhone was so radically different, exciting, and useful to potential users that within a short time, users flocked to it and established Apple as a market leader and that persists to this day...
